WitrynaActive substances often contain impurities which originate from manufacturing. According to the definition of Regulation ( EU ) No 283/2013, impurities in the technical active substance are considered relevant if they are particularly undesirable because of their toxicological, ecotoxicological or environmental properties. Witryna17 wrz 2014 · Based on a phenomenological model, we study theoretically the impurity effect in d-wave high-Tc superconductors in the presence of the charge-density-wave (CDW) order. Our results verify that the intensity of the resonance state induced by the impurity depends on the CDW scattering strength. It first increases and then … WitrynaThe material shall consist of 2,4-D together with related manufacturing impurities, in the form of white to brown crystals, granules, flakes, powder or lumps with faint phenolic … iphone 14 pro max glitches
